Application
EMCO magnetic level indicators series LI indicates the liquid
level of vessels and tanks locally without power supply.
The liquid level detection is safe, reliable and maintenance free.
Special types indicates the interface between 2 non
homogeneous liquids.
Reed switches can be added for alarm function or for
control of pumps and valves.
Remote indication of the liquid level via a 4-20 mA signal
(or HART protocol) is optional.
The LI level indicators are fully in compliance with PED 97/23 EC
 
Principle
 
The EMCO magnetic level indicator is constructed from a
vertical stand pipe made from a non magnetic material.
The side mounted types are connected to the vessel at
the top and bottom creating the principle of connected
vessels.
Inside the stand pipe a float containing a permanent
magnet moves up and down following the change of
liquid level.
On the outside of the stand pipe a transparent rail with
indicator flaps are mounted.
The small flaps hold small permanent magnets. The flaps
are bi-colour with colours red and yellow.
When the float passes the flaps, the flaps are rotated
180° by the magnetic field in the float.
The indicator shows the red colour up to the liquid level.
Above the colour is yellow
